Here's what I do when the upload form requires EPS files to have the
ending .eps:

I have a target in my Makefile tha uncomments the lines above and does
the renaming:

	for i in $(PROJECT)pics.[0-9]*; do \
	  cp $$i `echo $$i | sed -e 's/pics\./pics/' -e 's/$$/.eps/'`; \
	done
	for i in $(PROJECT)pics.t[0-9]*; do \
	  cp $$i `echo $$i | sed -e 's/pics\.t/pics/' -e 's/$$/.tex/'`; \
	done

I could make this the default behaviour, but FeynMP would depend on
operating system dependend external tools.

Cheers,
-Thorsten
